Objectives: This study aims to investigate the mediating effect of social support on the relationship between the viewing of sensational videos of idol stars through the mass media and the sexual openness of adolescents. Methods: This study used the 'Study on countermeasures against sexual commodification of adolescents through mass media in the smart era' conducted by the 'Korea Youth Policy Institute' in 2014 for the entire country as the main data. Variables consisted of socio-demographic characteristics of study subjects, video viewing, social support, and sexual openness. For data analysis, SPSS ver 23.0 program was used. Results: As a result of comparing the averages, male students (20.40) had higher sexual openness than female students (18.67), and high school students (20.27) had higher sexual openness than middle school students (18.05) at school level. By grade level, sexual openness increased from the first year of middle school (17.47) to the third year of high school (20.82) (p<0.001). In order to verify the mediating effect of video viewing on the effect of adolescent social support on sexual openness, 3-step mediated regression analysis and Sobel test were conducted. As a result, video viewing had a significant effect on sexual openness through social support (p<0.001). Conclusion: Rather than obscuring the environment of mass media unconditionally, creating an atmosphere according to the tendency of realistic social support and reinforcing emotional education will help prevent the adverse effects of reckless sexualization of adolescents.

Holographic diffuser(HD) layer was demonstrated to be located inside LC cell for a transmissive LCD of TFT-array on Color Filter structure. Master pattern of this layer was generated by holographic method and this pattern was replicated by the stamping of the master pattern on UV resin. Combined with a compensation film, TN-mode LCD with this layer showed improved viewing angle characteristics, especially along the up-down direction.

We have developed a high performance vertical alignment TFT-LCD, that shows a high light transmittance, and wide viewing angle characteristics with an unusually high contrast ratio. In order to optimize the electro-optical properties we have studied the effect of cell parameters, multi-domain structure and retardation film compensation. With the optimized cell parameters and process conditions, we have achieved a 24" wide UXGA TFT-LCD monitor (16:10 aspect ratio 1920X1200) showing a contrast ratio over 500:1, panel transmittance near 4.5%, response time near 27 ms, and viewing angle higher than 80 degree in all directions.

Even if auto-stereoscopic and polarization based 3D displays are not working with the same principles, their common aim is to provide two different images in the eyes of the observer. In this paper we show that Fourier optics instrument for viewing angle measurements can be applied to both types of displays. Luminance measurements are made at different locations and what will be seen by an observer in front of the display is predicted. Precise 3D characteristics can be derived and direct comparison becomes possible.

본 연구에서는 조선후기 한양의 세시풍습과 명승을 기록한 "경도잡지(京都雜誌)"에 꽃놀이 명소로 등장하는 네 곳-필운대(弼雲臺), 북둔(北屯), 동대문 밖, 서대문의 천연정(天然亭) 등-을 대상으로 한다. 관련 문헌기록을 통해 각 명소들이 구체적으로 어떠한 경관요소들로 구성되고 방문객에게 어떻게 체험되었는지를 살펴보았다. 경관특성은 물경(物境), 정경(情境), 체험행위로 세분하여 분석하였다. 연구 결과, 대표적인 물경은 꽃이었으며, 꽃과 함께 술, 술잔, 술병 등의 음주와 관련된 물리적인 요소와 시 짓는 모임인 시회를 즐기는 장면도 등장하였다. 또한 이용 주체들이 물경에 의미를 부여한 정경의 도출을 통해 주체들이 공간에 성대해 갖는 의미를 해석하고자 하였다. 이를 통해 본 꽃놀이 명소의 의미로는 첫째, 풍류를 향유하기 위한 공간이라는 점이다. 문인들이 모여 꽃을 구경하고 술을 마시며 시회를 여는 등 각 공간들을 문화 창작의 거점으로 활용되었다. 둘째, 주체들이 각 장소에서 묘사한 정경에서 나타나듯, 방문객들은 공감각적인 완상을 통해 경관을 즐기는 것을 확인하였다. 이로써 꽃놀이 명소는 단지 꽃을 감상하는 것 이상의 감각적 체험의 장이었음을 확인하였다. 전통적인 꽃놀이 명소의 경관특성을 도출한 본 연구는 우리 선조들이 여가의 한 형태로 즐긴 꽃놀이와 그 공간이 갖는 의미를 추적하고 한국적인 꽃놀이 명소를 계획함에 있어 기초적인 자료가 될 것이라 판단한다.

3차원 완전 결상에서 동적 배열 렌즈 방식을 사용하여 해상도를 향상시킬 때, 해상도 향상 특성을 조사하였다. 렌즈 배열의 이동 방향 및 이동 거리에 따라 관측 해상도가 달라짐을 컴퓨터 합성 완전 결상을 이용하여 보였다. 이를 통해 효율적으로 관측 해상도를 향상시킬 수 있는 렌즈 배열의 이동 조건을 찾을 수 있다.

We investigated the improvement using a new patterned double twisted(PDT) vertical-alignment(VA) cell mode on a homeotropic alignment layer. Good voltage-transmittance curves for negative dielectric anisotropic nematic liquid crystal (NLC) using a new PDT-VA cell without a negative compensation film were obtained. The viewing angle of a new PDT-VA cell without a negative compensation film was sider than that of a conventional VA cell. Finally a few fabrication processes using a new PDT-VA cell mode can be achieved by only one-side rubbed substrate.

천동동굴의 관람대상물의 분포는 하나의 광장을 중심으로 밀집 분포하고 있다. 이러한 동굴의 형태 특성상 관람루트도 스푼형을 이루고 있다. 그러나 실제로 관광객은 정해진 통로를 따라 이동하면서 조명이 비추어진 지형지물을 관찰하는 관람 형태로 이루어지고 있다. 이러한 관람방식에서 생기는 문제점을 두 가지 관람유형에 따른 네트워크 분석을 통해 관람 포인트의 특성과 문제점을 도출하였다.

The purpose of this study was to identify how characteristics of young children (sex, age, temperament), mothers (employed or unemployed, intimacy between mother and child, parenting attitudes), and home environment (pet, TV/Video viewing) relate to young children's empathy and to examine the relative effects of then variables on young children's empathy. The subjects for this study were 300 3-, 4-, and 5-year-olds selected from kindergartens and day-care centers in Busan. Data were analyzed via t-test, correlation, and multiple regression. Results showed that girls had higher empathy score than boys. Young children's empathy was positively correlated with the sociability of young child's temperament, intimacy between mother and young child, reasoning guidance, affect, achievement of parenting attitudes, and parental intervention toward young child after TV/video viewing. However, young children's empathy was correlated negatively with authoritarian control of parenting attitudes. Among then variables, young children's sex was the most significant variable.

An inverse-twisted-nematic (ITN) transflective (TRF) liquid crystal (LC) display, where two imprinted optical films (IOFs) with surface microstructures are embedded was developed. One of the IOFs serves as an in-cell patterned retarder with multioptic axes, and the other behaves as a viewing-angle enhancement film. In the presence of an applied voltage, the surface microstructures on the IOFs provide the spontaneous twist of the LC from a vertically aligned state to a $90^{\circ}$ twisted-nematic (TN) state in the transmissive part, and to a $45^{\circ}$ TN state in the reflective part. The developed ITN TRF LC display exhibits high transmission and reflectance, fast response, and wide-viewing characteristics, along with achromaticity.
